Hydroprocessing (SCANfining™)  

SCANfining™ technology offers a cost-effective solution for meeting the low sulfur requirements of gasoline. The technology removes sulfur with minimum octane loss by utilizing a jointly developed ExxonMobil/Albemarle catalyst technology coupled with ExxonMobil’s hydroprocessing design. With over 40 licensed units in operation, ExxonMobil brings demonstrated industry experience in offering customizable solutions to meet today’s refining challenges.

Innovation  

This robust catalyst system was designed through years of experimentation, resulting in a highly selective catalyst for removal of sulfur from FCC full-range naphtha. The technology allows multiple benefits, such as minimum hydrogenation of olefins (thus preserving octane), and reduced hydrogen consumption – up to 30-50% less than conventional hydrofinishing.

Flexible solutions  

ExxonMobil’s customized solutions enable investment staging to meet the site-specific sulfur requirements. Depending on the product sulfur requirements, one or two reactors can be offered. SCANfining can be retrofitted using existing equipment, and there are multiple configurations that can best adapt the process to site-specific conditions, resulting in optimized investment. Zeromer™ technology can also be used for the catalytic destruction of mercaptans. Operational feedback and further research and development improve this technology continuously.

Proven global operations  

SCANfining technology has been proven worldwide in successful commercial use since the 1990s. With over 40 units in operation or design around the world, SCANfining is a proven, attractive option for competitively meeting increasing stringent gasoline sulfur specifications.
